Quick update:
I called Victor (real nice guy) and he said that he doesn't rebuild the actual mechanics for regulators. He told me to call SMS hood hinge repair. They don't (SMS) rebuild them either. I emailed Resto Ricks (another good guy) and he doesn't rebuild them either. I called Roger Gibson's and he doesn't rebuild them either... A couple of the people I spoke w/said that a lot of the parts in regulators aren't available...
I will try Stanton's idea once it warms up and hope it works.
